Mate the realtek bluetooth module for the board 5.0 /wifi ( not sig fees my apologies late at night) is currently 3.90 USD a board, and was $ 4.5 in 2022. The alibaba ones will be using the mediatek solution as the chinese use them primarily in all their devices as its the cheapest of the bunch. As i said previously, qualcom is the best of them all and is used by the majority of high end premium devices, realtek is a mid range device chipset,The Qualcom chip supports rapid charging and 13 hour battery life, realtek have never got near that, so perhaps that is what they have been developing for the new GEN 4.
